Tom is an archaeologist interested in the transition from non-hierarchical human communities, the pathways along which this transition was achieved, and variability in forms of Holocene social organization. More specifically, his research addresses the (somewhat counter-intuitive) emergence of social complexity in environments which might be expected to discourage such emergence, particularly on islands in the Mediterranean, Caribbean, and Pacific. He is especially interested in how small-scale and short-term adaptive strategies can drive unintended social and ecological change at much larger scales. Tom currently co-directs fieldwork which informs this research in Sardinia and in Micronesia.
